Top 5 for me in no particular order:
Battlestar Galactica (new version)
I’m sure I’m forgetting one that i’ll kick myself for later. Also Stranger Things currently one of the best shows going round. Plan to watch the Sopranos over the summer.
The Office (UK)
Always Sunny In Philadelphia
Honerable mentions to Curb your enthusiasm, Arrested Development, Eastbound & Down, Parks & Rec, 30 Rock, Black Adder, Alan Partridge and Flight of the Conchords.
